New pistons/rings for EA82Turbo 1800 ?

[ZRX Doug]

Ouch! We'll have to respectfully agree to disagree. While some of the flathead guys would indeed have jumped at the latest & greatest, the following week you'd have found them whittling away at their newly purchased engines with the same tools & techniques they were using on the old ones..but the fact is that quite a few of the flattie fans still exist, and they've continued to refine this "dead" engine with very little aftermarket support.

The "exotic modern tech" angle hasn't got a thing to do with it..an IC engine is an IC engine, makes no difference if it's made today out of unobtanium cast in zero-gravity conditions or if Henry Ford built it by pouring molten iron over wet sand in his backyard..both will still respond to the same mods.

 

As to what I "think" can be done..I don't THINK it, I know it. I've been building automotive & motorcycle engines for the past thirty freakin' years (yeah, 14 years old and built my first bracket engine, an AMC 390), and I've used the technique of resizing con-rods to obtain the CR I want on several occasions. It works, it's not a theory, it's a practice. And no, I'm not gonna rush out and build one of these engines to prove the point..I've no interest in it, and no use for it.

I offered a different point of view to a guy who was seeking to change his compression ratio on the cheaps. Doesn't matter what flavor of engine he's running, it'll work on your choice of mills also.

 

 

 

Those flathead V8 guys would have jumped at the chance to drop in an engine twice as powerfull that can be had for the price of a performance carb.

 

Besides that there's quite a difference betweent flathead tech, and the engines of today (or even of 20 years ago). Not the least of which is material sciences, and manufacturiing techniques that cannot be duplicated easily by the average modifier.

 

It's not a matter of *if* it could be done - sure it could. New rods, pistons, and heads/studs (biggest problem by far) would easily bring the EA82T up to snuff quickly - to the levels of performance seen in modern engines. We all know that. The issue IS the cost, and there is NO way around it. People have hashed this out many, many times. When you can build a decent EA82T for the price of an EJ22 then maybe it will be viable - till then it's acedemic - arm-chair B$ that will never come of anything. Spare us yet another long thread about what you *think* can be done, and what you could *theoretically* get out of it. Get out there and DO IT if you think it's such a viable option.

In off the shelf stuff (if its still available here) I guess EA82-T or if the N/A EA81 piston is suitable and still 8.7: static CR - possibly better .

 

 

Anybody got any pics of these EA81 pistons? And are they for sure a direct fit for the EA82? Or do they need to be modified?

EJ swaps are cool and great, but not everyone is going to do a conversion. It's alot more than most people want to tackle.

 

So you are advocating that people who don't want to pull an engine and install another one should pull their existing engine, tear it completely down, rebuild it with custom, expensive parts, reinstall it and then install completely custom management in order to get the same performance, and in all probability, less reliability?

 

That's silly, very expensive, and time consuming.

 

There's little need for this thread anyway - the EA82/T has been anyalized to death for years on this board. Use your search feature. The conclusion: install an EJ if you don't like slow and effecient.

 

The EA82 is a decent engine, but it's not suitable for performance mods. Economically it's far better to start with an EJ.

 

People have a tendancy to beleive (and defend that beleif) that what they own - what they have chosen - is the *best*. Sadly that's not always the case. I own 2 EA82's currently (and no EJ's currently), and I've had many, many others in the past including T's. I like them for what they are, but I also recognize their limitations - which are too numerous to consider spending much time or energy to overcome when for a fraction of the price I could get just as much KNOWN RELIABLE power from an EJ.

There is ALOT more involved in a swap than just droppin in a motor. First you have to buy an adapter plate($185) Then a motor($300-1000 depending on conditon and type)Then a whole Management system or all the extras and ECU from a donor car($?) Then you gotta get FSMs to make sure you wire it right. it's alot of work and money. And not everyone is gonna do it. And It is not what this thread is about. He didn't ask should I do an EJ conversion. He asked about the EA82t. Lots of us are happy to do our tinkering with EAs. If you wanna do an EJ swap fine. But don't be negative towards people who want to do stuff to there EA.

You have a tendancy to believe what you think and want from a vehicle are the "best". Sadly, that is not always the case.

I am here to answer questions that are asked, and ask my own. Not to tell others what to do.

There's a board member (rguyver) that makes them for $100. Extremely high quality computer CNC part too. He had 5 of them at the show in August.

 

Then a motor($300-1000 depending on conditon and type)

 

$250 for a shelf engine, $149.99+$50 core for a yard engine. That's COMPLETE engine assembly.

 

Then a whole Management system or all the extras and ECU from a donor car($?)

 

$25 for the harness, and $35 for the ECU at the yards.

 

Then you gotta get FSMs to make sure you wire it right.

 

All availible online in PDF. Just have to print em.

 

it's alot of work and money.

 

Still less money and work than building a Hi-Po EA82 that will be reliable.

It's not a matter of telling anyone what to do. It's a matter of telling people what's smart and what isn't. Wasting your time is your right - just don't expect anyone to not think ill of the logic.

the cheapest and best alternative is to get an entire vehicle. it's not hard to get an entire EJ vehicle for next to nothing. i've passed up one free one already this year and it wasn't even wrecked. to get one wrecked or with a bad transmission for chump change is also very easy to do. EJ22's can be found really cheap as well.

 

the other important question is if you're doing the work yourself. if not then the cost of a swap could be considerably more than an EA82 rebuild. finding a random shop (assuming you have no connections or whatever) willing to do this around this area is nearly impossible, if you do the prices are insane. around this area it would be cheaper to pay someone to rebuild an engine than do a custom swap if you're paying someone to do all the work and don't have contacts/friends/people helping you.

SERIOUSLY, please, GD is JUST PLAYING THE DEVILS FRIGGIN ADVOCATE!!!!!!

 

 

let it DIE and let him say what he will, posting and posting like this is just a bloody pissing match. STOP DOING IT, and if you want to continue to discuss ideas for an EA82 build, dont let him derail it!!! you made your point, gloyale.. as did GD.. what does furhter disagreement do to help either of your cases?? you are both really smart guys, and guess what? you are BOTH really set in your opinions and its only making you both look childish to continue this sort of penis-showing game.

 

please.. as you have both said, its been beaten like a dead horse.. why is it that you both say that, and then go back to beating the horse??

 

Can we maybe do some self-moderating here???

Hmm ok . Guys the reason I was looking into this was because I thought there may be a chance to improve the thing and have it fall back in . I have had a cursory glance at EJ20 conversion threads here in Australia but baulked at the wiring dramas . Its very easy to count the costs of upgrading the EA82-T and comparing it to fitting the EJ turbo option . Blind Freddy can see that the EJ is a far more modern design so more potential . I'm new to Subys so its a very steep learing curve for me ATM . Actually currently trying to solve the L series suspension limitations with Impreza/Liberty (Legacy in US) bits .

 

Hi Doug , no offense intended . I guess we have different ideas on quench for detonation supression and compression ratio . We both know that trying to get what we want from production heads/pistons is difficult and sometimes not econimically viable . I have similar ideas to what Corky Bell mentions in his book Maximum Boost purely because I've seen like ideas work .

 

Thanks everyone for their input , cheers Adrian .

[ZRX Doug]

No offense taken..just trying to give you a new angle or two to look at things from.

[discopotato03]

Am hearing rumors that Aus spec EA82 NA may have had 8.7 pistons to go with the garbage ULP we had in that era .

Please update us. That would be something, not TOO expensive to get a set shipped.
